Mr. Popper's Penguins

US true first — Little, Brown and Company, Boston, 1938. The first British edition followed from George G. Harrap (London, 1939), in blue cloth; it is collected in the UK but is a first thus and does not carry precedence. Both editions are collected; only the Little, Brown 1938 is the true first. Robert Lawson's own key titles sit apart and have their own firsts: The Story of Ferdinand (Viking, New York, 1936, text by Munro Leaf) and Rabbit Hill (Viking, New York, 1944).
